Inthe; drawings, l0 designates the body oiC the iron, ll hthe cover thereon, l2 the handle connected with said cover, 13 the gas eupply pipe connected with the body l0, and l-l an elongated lnirner applied within the hollow interior of the body l@ and resting agrainSt' theliat bottoni thereof. The body l() ie ot conventional outline, being pointed at one .end and having sides diverging' theretronnto the rear end of said body which is reasonablybreath as shown. '.lhe body l() has a hollow interior and is cast. with an entirely open upper end, and

Vthe sideS oi? thebody l0 are formed in their upper portions with elongated eide opening 15, while the rear end of said body is foi-ined with openinge` lo anda sinall lower opening 17.l The rear end of the body is also formed ll-with an opening 1S to receive the lower end of the gas supply pipe lZ-l which threaded to engage a threaded hole in the rear end ot the burner il and clamped in desired position by nie/aus,` of a nut 19.

The cover l1 tits entirely over the upper end ol the body l0, and at its torwardleml ie formed -with vars 10, which straddle a lng 2l .extending upwardly from the body, and said cover in hinged yto said body by ineens ot' a pin extending" tranevereelythrough e'aid ears and lug. 'llie rear end oi' the cover .ll il; ptovided with a spring latch having); a thunilrpiece anda dog U- the latter being adapted to enter an opening 25 in the rear end of the body 10 and detachably lock the rear end of the cover 11 upon said body. When it is desired to o en the cover 11 from the interior chamber othe body 10, the operator Will press on the thumb-piece 23 and turn the cover 11 upwardly ony its ,fronthinge. The cover 11 is cast integrally with standards 26 between which the handle l2 is secured on a rod 27, a shield 28 also being provided below the handle 12, as usual.

The burner 14 is a hollow elongated casting extending from the front to the rear of the body of the iron and provided at opposite side edges with a series of legs or feet 29 which rest upon the fiaty interior bottomi of the iron and support the burner 14 suitably above the same. The burner 14 contains an interior elongated tubular chamber 30 and is formed with burner orifices 31 at opposite sides of its lower portion, these orifices 31 leading downwardly and outwardly from the chamber 30 to the spaces between the legs 29, as clearly represented in Figs. 5, 6 and 7. The forward end of the burner 14 is closed, as shown in Fig. 1( and its rear end is open and internally threaded to receive the threaded end ot' the pipe 13, said pipe at its lower end being freely passed through the opening 18 in the lod.y of the iron and screwed into the threaded opening in the rear end of the burner 14. After the pipe 13 has been screwed into the burner 14 to a sufficient extent, the nut 19 may be tightened against the rear end of the body of the iron to serve as a. clamp for binding said pipe in rigid position and at such inclination with respect to its upper portion as may be desirable. The opening 17 in the rear end of the body of the iron leads into the space between the two rear legs 290i the burner 14 and serves to admit air to the upper tlat surface of the bottom of the iron.

The bottom ot the body ot the iron is formed with two series of horizontal inlet conduits 32, 33 for air, the conduits 32 being in staggered relation to the conduit-s 33, as shown in Fig. 8, and .said conduits 32, 33 at their inner ends7 which terminate at about the longitudinal center ot the bottom ot the iron, leading into vertical discharge openings 34, which are ot' somewhat greater .tiameter than the conduits and extend .ipwardly through the inner bottom snrt'are 'olf the iron centrally below the burner 14.

The air for supporting combustion is supplied through the opening 17, conduits 32, and vertical discharge openings 34. The openings 15, 16 are outlet openings and under varying conditions air may enter them also. The conduits 32, 33 are, drilled inwardly through the sides of the bottom ot the iron and extend only half way through said bottom, as shown in Fig. 8, and this arof the iron when the latter is in use.

rangement I have tound to be a distinct advantage in that each conduit is wholly independent of the others and not subject to counter currents as would be the case if the conduits were in communication with one another or ifconduits at both sides of the iron led into the same discharge openings 34. In the present" instance one discharge opening 34 is provided for each conduit and each discharge opening is independent of the other discharge openings. I also find it a distinct advantage to use a cast iron burner -14 and to support it directly upon the fiat bottom of the iron. rlhe manner of securing the burner in the body of the iron is also advantageous in that the burner is held stationary simply by screwing the lower end of the gas pipe 13 thereinto and locking said pipe by' means of the nut 1t). The parts of the iron may be readily assembled, and in use the iron has proven 'to be of very satis- 'factory character. One of the more essential features of the invention resides in the burner 14 and in its relation to the fiat upper Surface of the bottom of the iron, the gas outlet orifices 31 being reasonably close to said bottom and enabling the maintenance of a proper and uniform heat in the bottom The conduits 32, 33 and discharge openings 34 are also of very great advantage in assuring the proper combustion within the body l0.`

I am enabled with the use of my invention to maintain the lower portion ot the iron at a proper degree of heat tor effective use, while the upper portion ot the iron will .stand at a moderate heat: One of the dillieulties in the construction and use of gas heated sad irons has been the tendency of the flames to at times extend ont through the sides ot the iron, with the resultant danger ot igniting the clothes of the user of the iron, and this objection is wholly obviated by my invention, the sides ot my iron heilig closed at their lower portionsl above the conduits 32, and the flames troi the burner 1t being confined down against e upper flat surfare ot the bottom of the ii 1.

The gas pipe 18 ma) oe turned to any inclination best suited to the wishes ot the operator, and usually will be inclined toward the right, as illustrated in Fig. 3 and in said positionrigidly held by means ot the nut 19, but one advantage of my invention is that the pipe 13 may be turned to a reverse position or toward the lett troni the position shown in Fig. 3 so as to accommodate. theI iron for the use of a person desiring to operate, the same with the. let't; hand. l also provide the pipo f with a regulator valve 35 which is in the i'orm of a sleeve encircling the nipple ot the pipe and having a series of openings 3G to be placed more or less in register with a series ot' corresponding openingsl 37 leading to the interior of the lower porllt) . of bein tion of the nipple and the upper end of the pipe 13, the openings 36 being exposed to the .The iron as awhole has been designed with the view of securing maximum eiiiciency, of enabling the maintenance of a proper and uniform heat at the bottom of the iron, of obviating any'danger of the flames within the iron reaching the clothing of the operator or the goods being ironed, of preventing undue he'atmg of the upper portion of the iron, and of providing a construction of durable character' and capable real(dily manufactured and sold at reasona le e. pense.
